The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
vanity_appraise Appraise the rarity of a Solana address ~136
Appraise how rare a Solana address is: its detected vanity pattern, rarity score, rarity bits, tier, and expected grind attempts. Pure math on the Base58 address — nothing is stored. If the address has been published to the proof-of-grind gallery, the public entry is returned too. Read-only, no payment.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The Base58 Solana public key to appraise (32–44 chars). |
| prefixLen | integer | – | Override how many leading characters to treat as the pattern prefix. |
| suffixLen | integer | – | Override how many trailing characters to treat as the pattern suffix. |
No output schema declared.
No examples provided.
vanity_board Browse the vanity grind-bounty board ~166
Browse the public grind-bounty board: vanity-address bounties requesters have escrowed for the worker fleet to grind. Filter by status (open / all / settled), sort by recency, reward, or expiry, and paginate. Each bounty shows its pattern, USDC amount, difficulty, status, and timing. Read-only; posting a bounty is a separate x402-paid write on the HTTP API.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max bounties to return (1–100, default 24). |
| offset | integer | – | Pagination offset (default 0). |
| sort | string | – | Order: newest first, biggest reward first, or soonest to expire. Default recency. |
| status | string | – | Which bounties to list. Default open. |
No output schema declared.
No examples provided.
vanity_config Bounty market config: payout + asset metadata ~91
Read the grind-bounty market configuration: whether on-chain payouts are configured (can a winner actually be paid?), the settlement asset (USDC) and its decimals, which escrow networks are live (Base / Solana), the pricing band (floor + max atomics), the bounty protocol version, and the sealed-envelope scheme. Check this before posting to confirm the market can pay out. Read-only, no params.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
vanity_gallery Browse the proof-of-grind rarity gallery ~180
Browse the public proof-of-grind gallery: rare Solana addresses people have published with a verifiable grind receipt. Sort by rarity score or recency, filter by tier, minimum pattern length, or a substring the pattern must contain, and paginate. Each entry shows the address, pattern, rarity score/bits, tier, and an explorer link. Read-only.
| Name | Type | Req | Description |
|---|---|---|---|
| contains | string | – | Only addresses whose vanity pattern contains this substring. |
| limit | integer | – | Max entries to return (1–100, default 24). |
| minLength | integer | – | Only patterns at least this many characters long. |
| offset | integer | – | Pagination offset (default 0). |
| sort | string | – | Order by rarity score (rarest first) or recency. Default score. |
| tier | string | – | Filter to a single rarity tier id. |
No output schema declared.
No examples provided.
vanity_leaderboard Top grinders by USDC earned ~66
Rank the worker fleet: the top grinders by total USDC earned from winning vanity-address bounties. Each entry shows a worker id and its cumulative payout. Read-only.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | How many top grinders to return (1–100, default 10). |
No output schema declared.
No examples provided.
vanity_open List claimable open bounties for workers ~97
List the open, unexpired bounties a grinding worker can race to claim — the queue worker fleets poll. Each entry carries the pattern to grind and the escrowed USDC reward; the first worker to submit a verified, sealed key wins. Read-only discovery; submitting a claim is a separate write on the HTTP API.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max claimable bounties to return (1–100, default 30). |
No output schema declared.
No examples provided.
vanity_quote Quote the bounty price for a vanity pattern ~152
Quote how hard a Solana vanity address is and what to escrow for it. Give a Base58 prefix and/or suffix and get the expected attempts, rarity tier, and an honest suggested USDC bounty (atomic units) from the difficulty→price oracle. Pure function of the pattern — no wallet, no payment, fully read-only. Use this before posting a grind-bounty so you escrow a fair amount.
| Name | Type | Req | Description |
|---|---|---|---|
| ignoreCase | boolean | – | Match the pattern case-insensitively (cheaper, less rare). Default false. |
| prefix | string | – | Base58 prefix the address must start with (e.g. "THREE"). |
| suffix | string | – | Base58 suffix the address must end with. |
No output schema declared.
No examples provided.
vanity_stats Live grind-bounty market totals ~59
Get live totals for the grind-bounty market: how many bounties are open, how much USDC is currently escrowed, and how much has been paid out to winning workers. A quick pulse on market activity. Read-only, no params.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
